“It will be difficult not to be satisfied,” he told reporters after the match. “We scored a lot of goals and kept a clean sheet.

“We were fast and dangerous. We are confident and we must stay focused in every single game. Ludogorets were impressive in the first half.

“It is important to win our home games in the battle for the first place.”

Arsenal can secure their progression to the last 16 with a win against Ludogorets in Bulgaria, but, having been knocked out at the next stage in each of the previous six campaigns, gaining the seeded first position could be vital.
